A lot of Engineering projects and tutorials for the students to help them in their final year projects and semester projects.
In this article, you will learn about the working principles and applications of this electronic device. We’ll tell you about the design nuances of a control unit used in one of the most popular electrical motor types – a brushed DC motor.
Near the end of the datasheet document, you’ll find some application examples. The most important one for us is the bidirectional motor control using one channel of the L293D IC. Here is the given figure for that configuration.
Electronics and semiconductor manufacturers offer a rich selection of hardware and software components that you can use in your project. For example, in building a BDC motor controller circuit for the robotic lawn mower, we used STM32F4, which is part of the STM32 ecosystem for motor control.
I bent their leads on the other side so that they stay in position when I flip the board for soldering. As for the bigger components I used a masking tape to hold them in place when flipping the board.
Suppose the slider of the potentiometer is adjusted so that the voltage at its slider is 3V. Since the slider terminal is connected to A0 pin, the voltage at A0 pin will be also 3V.
Also the transistor acts as a switch. When the output from the Arduino pin 10 is LOW then there is pelo base current, the transistor is driven into cutoff region of operation and therefore there is pelo collector current. In this case there is pelo current flowing through the DC motor.
The library has hundreds of thousands of components so I didn’t have any problem finding all of the required components for this PWM DC Motor Speed Controller circuit.
While sensors offer obvious advantages, they come with disadvantages as well. Some sensors have low tolerance to dust, and require regular maintenance. Others operate properly over only a limited range of temperatures. The use of sensors, and the implementation of all the attendant circuitry, increases manufacturing costs; and highly precise sensors are of course the most expensive.
We’ll have to do this step just to have the TIM_HAL files added to our project by CubeMX. And also it gives us a startup configuration for the PWM channel of that specific timer module as we’ll see hereafter. This is the best way to keep the code generic and portable to any STM32 microcontroller.
If we start to reduce the maximum voltage at which the motor rotates at maximum speed, the speed of the motor also starts to reduce. In this way these enable pins are helpful to control the speed of the DC motor.
Using any method of connecting the wires, securely attach the potentiometer to the power supply using one wire, attached on both ends, or by connecting the components directly together.
We can use the Silk layer to add text to the board. Also we are able to insert an image file, so I add an image on of my website logo to be printed on the board. At the end using the copper area tool we need create the ground area of the PCB.
The circuit is connected in breadboard as per the DC motor speed control circuit diagram shown above. The pot here is used to adjust the speed of motor.
